MONTGOMERY W. HYER, OF NEW YORK, N. Y.

TEMPORARY BINDER.

To all whom it may concern:

Be it known that I, MONTGOMERY W. HYER, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Temporary Binders;and I do declare the following to be a full, clear, and exactdescription of the'invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to an improved temporary binder and the objectthereof is to provide a simply constructed and eliicient device of thischaracter which will reliably clamp and hold loose sheets in positionand from which said sheets may be readily removed.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts, aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings, Figure 1' represents a top plan view ofthe device applied with the clamping member in unlocked position; Fig. 2is a similar view with the clamping member in locked position; Fig. 3 isa transverse vertical section taken on line 3--3 of Fig. 2 Fig. 4 is aperspective view of the sheet supporting member detached; Fig. 5 is asimilar view of the clamping member detached and viewed from the top.

In the embodiment illustrated a supporting member 1 is shownpreferablymade in L-shaped form in cross section the bottom plate 2 being providedpreferably near its opposite ends with uprights 3 and 4 preferab y madein the form of flat bars and against which the upper and lower edges ofthe bound sheets are adapted to abut to hold them in alinement and onwhich the clamping member, to be described, is adapted to slide. Thevertical flange 5 is designed to form a limiting stop to hold the rearedges of the sheets in alinement and is preferably made of any height.

As shown, the bottom plate 2 is provided with one center ost or standard6 disposed intermediately of the ends of said plate and on which thepunched sheets are adapted to be inserted. It will be understood thatany desired number of these intermediate posts may be provided asdesired. A clamping member is preferably made in the form of aSpecification of Letters Patent.

metal plate 7 corresponding in widthto the bottom plate 2 and isprovided at its oppo site ends with apertures 8 and 9, of a widthslightly greater than the width of the up-- rights 3 and 4 and arrangedin position to slide over said uprights. These apertures 8 and 9 aremade of a length greater than the thickness of the uprights 3 and 4, fora purpose to be described. S ring plates 10 and 11 are fastened to saidplate 7 preferably on the upper face thereof adjacent to the apertures 8and 9 and these spring plates 10 and 11 are provided at their outer endswith T- shaped slots 12 and 13 the side walls of the stem portions ofsaid slots being bent slightly upward to form spring tongues forengaging the opposite edges of the uprights 3 and 4 when in lookingposition. The tongues of the plates 10 are arranged at the inner end ofthe aperture 8 and the tongues of the spring plate 11 are arranged atthe outer end of the aperture 9 thereby leaving a space at the outer endof the aperture 8 and at the inner end of the aperture 9 in which theuprights 3 and 4 may be slid freely when the clamp is being inserted orremoved. An elongated slot 14 is formed intermediately of the ends ofthe plate 7 through which the ost or standard 6 is adapted to slide andthe ength of said slot permits said plate to be moved longitudinally onsaid posts and uprights. In the use of this device the sheets 15 to bebound are punched, as shown, in the usual manner with slits extendingfrom the punched holes to the rear edge of the sheet to permit it to bewithdrawn laterally when desired. These sheets are placed in the binderwith the posts or standards as 6 extending through the punched holesformed in the sheets and with the upper and lower edges thereof abuttingagainst the inner faces of the uprights 3 and 4. After the desirednumber of sheets have been placed on these posts the clamping member 7is disposed thereon by passing the standard 6 through the slot 14 and bypassing the uprights 3 and 4 through the apertures 8 and 9 at the endsof said plate. After the plate has been placed in position it is movedlongitudinally to cause the spring tongues of the plates 10 and 1 1 toengage the opposite edges of said uprights to lock said plates inposition and by pressing down on said member 7 the sheets are tightlyclamped between it and the bottom plate 2 and securely held againstdisengagement.

When it is desired to remove or insert one or more sheets, the plate 7is moved longitudinally to unlock it and when the sheet is to bewithdrawn it is simply pulled laterally the slit at the rear of thepunched hole therein permitting it to be readily detached.- When a sheetis to be inserted the plate 7 is first removed the sheet placed inposition the plate again slipped over the standards and the uprights,moved longitudinally into locking position when it is pressed downwardlyand the sheets firmly clamped.

' From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claims.

I claim as my invention:

1. A temporary binder comprising a supporting base provided withlongitudinally spaced uprights, and a clamping member provided withslots to receive said uprights,

, spring metal plates attached to said clamping member adjacent to theslots therein, and each having a T shaped slot, the side Walls of thestems of said slots forming spring tongues, the tongues of one platebeing arranged at the inner end of one of the slots in plate at theouter end of the other slot.

2. A temporary binder comprising a base plate provided withlongitudinally spaced uprights, with a standard or 0st arranged betweensaid uprights, and a c ampi-ng member having apertures at its oppositeends for engagement with said upri hts, and an elongated slot formedinterme iately of its ends -for receiving said standard, and springmeans carried by said clamping member for engaging said uprights to locksaid clamping member in operative position.

3. A temporary binder comprising a supporting base L-shaped in crosssection provided with longitudinally spaced upright bars projecting fromthe lower arm thereof, and with a post formed intermediately of saidupright bars, and a clamping member having slots arranged to pass oversaid bars and post and provided with means for frictionally engagingsaid bars to hold said clamping plate in operative position.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
